在hdfs中是否有与“pwd”等效的内容？ [英] Is there an equivalent to `pwd` in hdfs?

问题描述

我试图做 hdfs dfs -pwd ，但该命令不存在。
因此，目前我正在采取 hdfs dfs -ls .. ，然后是 hdfs dfs -ls ../..。

I tried to do hdfs dfs -pwd, but that command does not exist. So currently I am resorting to doing hdfs dfs -ls .. followed by hdfs dfs -ls ../...

我也查看了 hdfs dfs 的命令列表，但没有看到任何显示有希望的。

I also looked at the command listing for hdfs dfs but did not see anything that looked promising.

有没有更直接的方法来找到绝对路径？

Is there a more direct way to find the absolute path?

推荐答案

hdfs dfs -pwd不存在，因为在从命令行运行命令时，HDFS中没有工作目录概念。

"hdfs dfs -pwd" does not exist because there is no "working directory" concept in HDFS when you run commands from command line.

你不能在HDFS shell中执行hdfs dfs -cd，然后从那里运行命令，因为HDFS shell和hdfs dfs -cd命令都不存在因此，工作目录的概念是多余的。

You cannot execute "hdfs dfs -cd" in HDFS shell, and then run commands from there, since both HDFS shell and "hdfs dfs -cd" commands do not exist too, thus making the idea of working directory redundant.

您的主目录始终是路径的前缀，除非它以/\".

Your home dir is always the prefix of the path, unless it starts from "/".
